Abstract
A method (200) and system (220) for range detection is provided. The system can include a sensing unit (110) for detecting a location and movement of a first object (401), and a processor (107) for providing a measure of the movement. The processor can convert the measure to a coordinate signal for moving a second object (124) in accordance with a location and movement of the first object. The system can include a pulse shaper (109) for producing a pulse shaped signal (167) and a phase detector (101) for identifying a movement from a reflected signal (166). A portion of the pulse shaped signal can be a frequency modulated region (312), a constant frequency region (316), or a chirp region (324). In one arrangement, the pulse shaper can be a cascade of all-pass filters (515) for providing phase dispersion.
